 geändert werden. Bei Maschinen mit einer von der   Arbeitswicklung getrennt angeordneten     Erregerwicklung konnte die   Änderung des Magnetfeldes auch durch ein Ab- bezw. Zu schalten von Windungen, die den Erregerstrom führen, herbeigeführt werden. Auch sind bei Erregerwicklungen, welche getrennt von der Arbeitswicklung am Ständer angebracht 
 EMI1.2 
 
Letztere Anordnung lässt sich aber gemäss der Erfindung auch dann   anwenden, wenn   die   Erregerwicklung   mit der Arbeitswicklung auf dem Läufer vereinigt ist. und zwar mit 
 EMI1.3 
 



  Die nene technische Wirkung bosteht darin, dass das Verhältnis von   Hrregerstrom zum   Arbeitsstrom ohne starke Einbusse an wirkungsgrad oder Leistungsfaktor verändert werden kann. Die   Widerstände   drosseln nicht den Hauptstrom, liegen auch nicht parallel zur 
 EMI1.4 
 weil die Widerstände gerade im Anlauf einerseits und bei hoch   über dem Synchronismus   liegenden Tourenzahlen andererseits sehr wirksam sind und somit eine   sehr zweckmässige   Regelung des Magnetfeldes ergeben. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

 be changed. In machines with an excitation winding arranged separately from the working winding, the change in the magnetic field could also be caused by a down or To switch windings that carry the excitation current are brought about. Also in the case of excitation windings, which are attached to the stator separately from the working winding
 EMI1.2
 
According to the invention, the latter arrangement can also be used when the excitation winding is combined with the working winding on the rotor. namely with
 EMI1.3
 



  The technical effect is that the ratio of excitation current to working current can be changed without any major loss of efficiency or power factor. The resistors do not throttle the main current, nor are they parallel to the
 EMI1.4
 because the resistances are very effective, especially during start-up, on the one hand, and on the other hand, when the number of revolutions is high above the synchronism, and thus result in a very useful regulation of the magnetic field.
